Launching Starcraft II through ForceBindIP

Hi, I'm trying to setup my twitch stream, and since my home connection is too slow for that, I was trying to use a 4G connection for the streaming part, but still wanted to use my home connection for the game itself, since it has a better ping.

I'm currently using ForceBindIP to achieve that, but I'm not quite sure which exe I should bind with my home connection in order to make it work.I tried with this command line: "C:\Program Files (x86)\ForceBindIP\ForceBindIP.exe" -i 192.168.0.3 "C:\Program Files (x86)\StarCraft II\Support\SC2Switcher.exe" but the Task Manager shows that the game is still running through my 4G connection.

I then tried "C:\Program Files (x86)\ForceBindIP\ForceBindIP.exe" -i 192.168.0.3 "C:\Program Files (x86)\StarCraft II\Versions\Base69232\SC2.exe" but I got an error message that said "icuin52.dll was missing".
